While the microcontroller accesses the program data (not the program code)
out of the data emulation memory provided by the microcontroller, the content
of the data emulation memory can simultaneously be modified by the calibra-
tion and development system through the XETK Ethernet interface. This pro-
cess enables adjustments of parameters, characteristic lines and maps
through the calibration and development system.

ETAS Hardware Description
XETK-S23.0 -User Guide 16
Using an additional measurement data memory area, the ECU microcontroller
can provide data to the calibration and development system by buffering the
data (DISTAB) and triggering the XETK to read the data via JTAG. The XETK
then reads, buffers, processes and sends this measured data to the PC.
The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
The power supply for the XETK-S23.0 is provided by a switch mode power sup-
ply, to minimize power dissipation.
4.2 ECU Interface
The XETK-S23.0 is connected via connectors CON1 and CON4 to the ECU with
two adapter cables (refer to Fig. 4-2 on page 16). The pin definition depends on
the application and the microcontroller type. In general, the ECU interface con-
sists of
• 1 ECU voltage line, which is not used for XETK power supply, but only for
detection of the ECU status, therefore the power consumption on this
line is negligible (refer to chapter 4.4 on page 17)
• 1 Reset line which allows the XETK to control the system reset of the
ECU
• 1 Reset line which allows the XETK to monitor the system reset of the
ECU
• 5 JTAG Debug line interfaces for the communication between the XETK-
S23.0 and the microcontroller
• 1 Watchdog timer disable line
•7 ground lines for proper shielding of the ECU interface lines

4.3 XETK Ethernet Interface
The XETK Ethernet interface can be directly connected to the PC via CON2
(refer to Fig. 4-3). No additional ETAS module is required for the access to the
ECU.
The interface is a standard full duplex 100Base-TX Ethernet interface using the
XCP protocol. The XETK Ethernet interface is integrated in the ETAS IP world
with automatic IP management and supports the open automotive "Universal
Measurement and Calibration" standard "XCP on Ethernet" (TCP/IP, UDP/IP).
The open XCP on Ethernet interface allows for connecting to the XETK-S23.0
with third party application softw are.
Fig. 4-3Location of the XETK Ethernet Interface connector (CON2)
4.4 Power Supply
The XETK-S23.0 requires a permanent power supply. It is typically powered
directly from the car battery. The input voltage may vary between 6 V and 36 V.
In case of higher input voltages to the XETK, additional voltage protection is
required. The XETK-S23.0 will also accept voltage dips down to 3V (for addi-
tional details of low voltage operation, see ISO standard 16750).
NOTE
The XETK Ethernet interface is not compatible with the ETK interfaces in
modules like e.g., ES910, ES590, ES591, ES592, ES593-D, ES595, ES1232-A.
The XETK Ethernet interface is compatible with the ECU interface of the
ES910 module and the Ethernet interfaces of the ES592/ ES593-D/ ES595/
ES600/ES88x/ES89x modules.
NOTE
Please see chapter 7.1.2 on page 32 for additional information regarding PC
requirements for the Ethernet interface.
CON2

ETAS Hardware Description
XETK-S23.0 -User Guide 18
From the input battery voltage, the XETK-S23.0 creates all necessary voltages
through switching power supplies on the XETK-S23.0. The power supply of the
ECU is not affected by the XETK-S23.0. An automatic switch ensures that the
power supply of the XETK-S23.0 is automatically switched on and off when the
XETK enters and leaves its standby (sleep) mode.
The XETK-S23.0 can be supplied with power through the six-pin connector,
CON4.
Fig. 4-4Location of the XETK-S23.0 Power Supply Connector CON4
4.5 ECU Voltage Supervisor
The ECU voltage (VDD) is monitored by the XETK to recognize whether the ECU
is switched on or off. Additionally, the ECU RAM standby voltage (VDDSTBY) is
monitored to determine if the standby RAM content is still valid. These two sig-
nals are only used for monitoring therefore the load current is negligible.
The XETK-S23.0 provides two opportunities to supply and supervise the ECU
RAM standby voltage:
• The XETK-S23.0 monitors the VDDSTBY supply on board the XETK. The
microcontroller’s standby power supply pin must be connected to the
XETK pin VDDSTBY.
• The XETK-S23.0 monitors the VSTBY pin, provided by the ECU connec-
tion. The microcontroller’s standby power supply pin must be connected
to the XETK pin VSTBY. The microcontroller’s standby power supply may
be provided by the ECU or by the XETK.
NOTE
The XETK-S23.0 only allows switching between reference page and working
page if there is a valid voltage at the sense pin and the working page has been
initialized by the calibration and development system.

bration and development system has downloaded data
since the last power failure. Switching between the Refer-
ence Page and Working Page is possible.
On Power supply has dropped under selected threshold:
- data retention of the calibration data manager in the ECU
is no longer ensured
- as soon as the XETK-S23.0 switches on again, the ECU
switches to the Reference Page.

system downloads data into the calibration data memory.
Otherwise switching to the Working Page is not possible.

4.7 Data Emulation and Data Measurement
The XETK-S23.0 is a serial XETK using JTAG as the primary microcontroller
interface. Typical for all serial (X)ETKs, the RAM used for data emulation and
data measurement is not accessible by the XETK until the microcontroller is
powered up and the startup handshake is performed.
Serial XETKs use the ETAS two-page concept, consisting of both a Reference
and a Working page.
The Reference Page is located in the ECU flash and cannot be modified by a
simple write access. All changes to the Reference Page must be done via Flash
programming.
The Working Page is located within the microcontroller's EMU RAM. The Work-
ing Page may be a portion of or the entire size of the EMU RAM. The EMU RAM
used for the emulation of calibration data must not be used by the ECU soft-
ware directly as general-purpose RAM. It is recommended that the EMU RAM is
permanently powered by the XETK or ECU. The XETK/INCA has the complete
control over the RAM used as Working Page and it's contents. When enabling
data emulation, the XETK establishes a basic startup configuration of the data
in the Working Page by copying the corresponding data in the Flash to the emu-
lation space.
To enable calibration, the Working Page must be activated. The process of
switching from the Reference Page to the Working Page and vice versa is
known as page switching.
The XETK-S23.0 supports Protocol Based page switching for all supported
microcontrollers. Page switching is done in microcontroller software by switch-
ing the overlay memory on (Working Page) and off (Reference Page) using
microcontroller overlay registers. The XETK-S23.0 does not directly control the
microcontroller overlay registers. Instead, the XETK-S23.0 and microcontroller
software use a simple communication method with a shared mailbox in RAM.
The XETK uses this mailbox to request and monitor page switching; the micro-
controller software is responsible to service this mailbox and perform the page
switches. Using an overlay modification description, also in RAM, the XETK pro-
vides the necessary information of how the overlay registers need to be modi-
fied to realize the page switch which is requested.
The XETK-S23.0 can access both the Reference Page and the Working Page,
regardless of which is active from the microcontroller’s point of view.
Another important restriction is that no access to the memory is possible, while
the ECU is not running. To enable a coldstart measurement in spite of this
restriction, the coldstart measurement procedure is defined to give the user the
feeling of a parallel XETK.
